		<p>By default, Capella elements don't have any SID. As soon as a transition is performed, </p>
		<ul>
			<li>If the SID of the source element is null, it is initialized with the technical ID of the source element</li>
			<li>If the SID of the source element is not null (i.e. the system is already a sub system, result of a transition), the SID is kept.</li>

		<p>In the above figure, the

		<h2 id="Sub-System_Model">Sub-System Model</h2>
		<p>The target element gets a new technical ID, its SID is the one of the source element in the System model.</p>

		<p>In the above figure, the
